Lab-Aids: Making and Modeling Polymers Kit


Every day, students use numerous products made of plastic. This kit introduces the structures and properties of the polymer molecules that make up all plastics. Students first investigate the properties of a linear polymer found in white glue, and then add a cross-linker to explore the properties of the resulting cross-linked polymer. They then use paper clip models to investigate the molecular structures of monomers, polymers, and cross-linked polymers, and explore how their structural differences alter the properties of the molecules. Developed by SEPUP.
